🐈‍⬛🔐 HASHCAT — PUT YOUR PASSWORDS TO THE TEST A password can look strong and still fall short when its hash is properly audited. Hashcat helps security professionals evaluate password resilience using different hash modes, wordlists, masks, rules and GPU acceleration — making it an essential tool for authorized password-security assessments. ⚡🛡️ 💬 Comment “HASHCAT” for the program link! #Hashcat #PasswordSecurity #CyberSecurity #SecurityTesting #CyberKid

Linux "chmod" Permissions Explained 🐧 One of the most important Linux commands in Production is "chmod". It is used to manage file and folder permissions. Permission Numbers: Number| Permission| Meaning 0| "---"| No permission 1| "--x"| Execute only 2| "-w-"| Write only 3| "-wx"| Write + Execute 4| "r--"| Read only 5| "r-x"| Read + Execute 6| "rw-"| Read + Write 7| "rwx"| Read + Write + Execute Most Used "chmod" Examples - "chmod 777" → Everyone gets full access. - "chmod 755" → Owner: "rwx", Group: "r-x", Others: "r-x". - "chmod 775" → Owner & Group: "rwx", Others: "r-x". - "chmod 700" → Only owner has full access. - "chmod 600" → Owner can read and write only. - "chmod 644" → Owner: "rw-", Group & Others: "r--". - "chmod 664" → Owner & Group: "rw-", Others: "r--". Easy Formula: - Read = 4 - Write = 2 - Execute = 1 Examples: - "7 = 4 + 2 + 1 = rwx" - "6 = 4 + 2 = rw-" - "5 = 4 + 1 = r-x" - "3 = 2 + 1 = -wx" Understanding "chmod" is a small step in Linux, but a big step toward becoming a better DevOps engineer.
